“…Quantitative structure‐activity/property relationship (QSAR/QSPR), an important area in the chemical and biomedical sciences, searches the relationship between compounds and corresponding biological activities or chemical properties . In order to obtain this relationship, a variety of statistical learning methods have been proposed in QSAR/QSPR, including multiple linear regression (MLR), principal component regression, partial least square (PLS) regression , decision tree , support vector machines , random forest , boosting , and so on. In QSAR/QSPR studies, the chemical structure of compounds is represented by several descriptors, such as molecular constitutional, topological, shape, autocorrelation, and charge descriptors.…”
